Abstract (en)
A circuit breaker closing actuator and a method of operation is provided. The closing actuator (72) is disposed to communicate and receive signals (94) from a trip unit (48). The trip unit (46) includes a communications to transmit and receive data and signals from a remote location. The trip unit (46) transmits a signal (94) to the closing actuator (72) in response to receiving a closing signal from the remote location. The closing actuator (72) validates the signal (94) and activates a driving circuit (86) if the signal (94) is validated. The driving circuit (86) enables power to a solenoid (68) that closes the circuit breaker.
